Giada De Laurentiis slices finger during live Thanksgiving show

Holy mascarpone! Celebrity chef Giada De Laurentiis carved more than a turkey during Food Network's Live Thanksgiving special on Saturday.

The "Giada at Home" star sliced her finger with a knife during the culinary live broadcast with colleagues Alton Brown, Bobby Flay and Ina Garten. The carving occurred when her knife slipped as she was slicing a turkey roll she'd prepared, and the incision went into her nail bed and ran from her index finger up to her perfectly manicured nail.

"It throbs a little bit," she said on a Monday appearance on the "Today" show.

"I was slicing my turkey porchetta," she added. "I was slicing it in the background to feed it to Bobby, Alton and Ina and, unfortunately, I guess I just sliced through my finger at the same time. When I realized it, I went to the sink to put pressure to see how big it was."

There was quite a bit of blood, she said, "which I think Ina really felt uncomfortable with. I think everybody kind of freaked out.

"We don't do live television usually on Food Network, so these things usually can get hidden. It couldn't get hidden."

The 43-year-old chef sought medical attention, Brown announced after a commercial break, and returned to the broadcast about 15 minutes later, RadarOnline reported.

"She seemed to go pale and got very quiet putting pressure on it and whispering to Ina that it was bad," a witness told the site. "She looked like she was about to faint."
